                       throws IllegalArgumentException

Description copied from interface: NodeFunction

Apply the function to the list of nodes passed as arguments and return the result as type T. Throws IllegalArgumentException if the function cannot be applied to the nodes passed as argument or the number of arguments is not correct.

context - the context of the execution. Same as using the NodeSelector '.' as parameter.

args - a nested list of KiWiNodes

Returns:

Throws:

IllegalArgumentException
